51094 - Problems when using sortStaticsLast="true" in XUL menus

Status: VERIFIED DUPLICATE of bug 48774

(Core :: XUL, defect, P3)

Description

[cata]

I first discovered this when trying to reorder the charset menu with the statics 
last and the template-generated items first. But then I noticed that the problem 
was already there in the only other menu using this ordering: View > Languages 
and Web Content

So, in order to see this bug, go to the View > Languages and Web Content submenu 
and you'll notice that the static items are duplicated. While this normally is 
just a nuissance, if those items happen to be submenus (as is the case in the 
charset menu), I get assertions because of duplicate nodes and the submenus fail 
to get filled up with items.

Some source code pointers: 
/rdf/content/src/nsXULSortService.cpp, line 333
/xpfe/browser/resources/content/navigatorOverlay.xul, line 260

This is pretty serious, as it is blocking a nsbeta3+ bug: 47343. I am assigning 
to Chris, but please reassign to whomever is owning this.
